“…The Meso‐Tethys opened between the Cimmeride terranes and Gondwana in the Permian; it closed in the Late Jurassic‐Cretaceous (Y. Ma et al., 2018; Metcalfe, 2021; Wei et al., 2022). The Cimmeride terranes included the South Qiangtang and Sibumasu terranes in the east, and Iran, Afghanistan, and other terranes in the west (X. D. Wang et al., 2021; Wei et al., 2022) (Figure 1a). They accreted onto the southern margin of Asia in the Triassic, marking the closure of the Paleo‐Tethys (Metcalfe, 2021).…”

The drift history of the Lhasa terrane from Gondwana to Asia plays a crucial role in understanding the Tethys evolution and true polar wander (TPW). However, few reliable paleomagnetic results from Jurassic strata are currently available for reconstructing its northward journey. We performed a combined paleomagnetic and geochronological study on Bima Formation strata in the Xigaze area. Combined with previous results from the Sangri area, our results reveal a paleolatitude of 8 ± 4°S at ∼180 Ma for the reference point (29.3°N, 90.3°E). Along with other paleomagnetic results from the Triassic to Cretaceous, our new results suggest that the Lhasa terrane motion accelerated from ∼2 cm/yr during ∼220–180 Ma to ∼17 cm/yr during ∼180–170 Ma. Paleolatitude information of the North Qiangtang terrane and Tethyan Himalaya is calculated from paleopoles that meet five criteria, which include (a) structural control, (b) well‐determined rock age, (c) stepwise demagnetizations, (d) a minimum of 25 specimens or 8 sites are contained, and (e) robust field or reversal tests are provided. Both terranes also show significant acceleration during their northward motion, which may be related to oceanic slab subduction. Thus, all Gondwana‐derived microcontinents seem to share a significant acceleration during their northward motion. In addition, recent paleomagnetic results from volcanic rocks dated at ∼155 Ma subdivide the overall northward motion during ∼170–130 Ma into two stages, which include a southward drift during ∼170–155 Ma followed by northward motion during ∼155–130 Ma. These results support the fast Late Jurassic TPW during a ∼10 Myr time span.

“…(2000, 2003) consider that the Central Qiangtang high pressure rocks (also named Central Qiangtang Metamorphic Belt; Figure 1b) represent an exhumed metamorphic dome rather than an in situ suture zone. Conversely, recent paleomagnetic data tend to support the presence of a large ocean between the North and South Qiangtang, at least during the Permian: they reveal that the North Qiangtang terrane rifted away from Gondwana prior to the Permian (Song et al., 2017) and was near the equator by late Permian times (Ma et al., 2019), whereas the Permian strata in the South Qiangtang terrane presents evidences of higher latitudes at that time, such as glacio‐marine deposits and cold‐water fauna (Shangyou et al., 1990; X. Wang et al., 2021).…”

The Tibetan Plateau was formed by intense Cenozoic shortening (up to 1,100 km) of a composite “proto‐Tibet,” itself the product of a long Paleozoic and Mesozoic history of accretion of Gondwana‐derived continental fragments and volcanic arcs against the Asian continental margin. The difficult access and the scarcity of outcrops have long limited the possibilities of studying these Mesozoic suture zones in the heart of the Plateau. In this work, we present new U‐Pb and 40Ar/39Ar ages from the highly deformed units of the Yushu mélange, along the Jinsha Suture in the northeastern Qiangtang terrane. Early Triassic (c. 253 Ma) to Middle Jurassic ages (c. 165 Ma) complement the existing data set and help to refine the chronology of the Paleo‐Tethyan oceanic subductions which have structured the northeastern part of the Qiangtang terrane. The Yushu mélange records at least three successive tectono‐magmatic events. The opening of a back‐arc basin during the northward Paleo‐Tethyan subduction along the Longmu Co‐Shuanghu Suture during Early to Middle Triassic; then its closure during the southward subduction of the Songpan‐Ganze Ocean along the Jinsha Suture in Late Triassic. Finally, a shortening phase related to the continental collision of the Songpan‐Ganze and Qiangtang blocks from Late Triassic to Early‐Middle Jurassic. No evidence for any high‐ or mid‐temperature Cenozoic reactivation of the Jinsha suture in our study area is recorded.
